To all whom, t may con/cern. i purpose. The indicator (shown in Figs. land Be it known that I, ARTHUR ALEXANDE 2) consists of a button or head D, having a SPARKS, a citizen of the United States, and a shank D', adapted to engage the eyelets C. resident of San Francisco, in the county of To prevent accidental loss of the indicator 55 5 San Francisco and State of California, have and to hold it steady, I connect it with the invented a new and Improved Calendar, of calendar base or frame A by means ot' a which the following is a full, clear, and exact string, cord, or equivalent element, and prefdescriplion. erably said element is constructed with-a My invention relates to that class of calenview of keeping it taut.

The object of my invention is to furnish a at F. Instead of the elastic string I may emcalendar of the above-indicated class which ploy a coiled-wire spring E, as shown in Fig. 65 will be simple, strong, easy to operate, and Li, this spring to be attached to the indicator' in which the indicator will be securely held and to the calendar-frame in the saine managainst accidental displacement. ner asthe string E.

In Fig. l I haveshown In Fig. the individual fastening devices 85 the ordinary type, in which the calendar conconsist of pegs or pins C2, secured to the backsists oi' a backing or frame A, to which are seing A and projecting forwardly through percured a series of superposed sheets B, each forations C of the sheets B. The indicator corresponding to one ot' the twelve months of is a disk D6, perforated in the center, as at the year. 'lhe invention is, however, also D7, to receive the pins C2 and having an an- 9o 4o applicable to calendars having a greater or nular groove for the end ofthe string or other smaller-number oisheets. These sheets have attaching connection E. the customary spaces B", in which are prolt will be understood that in each case the duced the successive date-numbers.

The connection E keeps the backing A. Incidentally, these eyelets the indicator attached to the calendar-frame, roo 5o afford a firmer connection between the sheets and as the said connection is always taut, B than the means usually employed for this and in fact under alongitudinal strain, there is a constant pull exerted upon the indicator, keeping it in Iirm contact With its holder or fastening device and preventing the indicator from becoming detached. Furthermore, the string or connection E will alvvays be in a straight line, and thus forms a guide for the eye.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A calendar, having a frame or backing and individual date-spaces, individual ho1ders or fastening devices, one in each of the date-spaces,an indicator adapted lo be secured to any one of said fastening devices,
